Finally, microbial fermentation has been studied as a promising method for removing cadmium from food. various industrial uses such as NiCd batteries, plating, pigments and plastics (ATSDR 1999). Cadmium is also found in some industrial paints and may represent a hazard when sprayed. Cadmium (Cd) is a toxic non-essential transition metal that poses a health risk for both humans and animals. doi: 10.1007/s00204-010-0544-6. Human beings get exposed to cadmium through the foods they take and in the places they live or work. When released into the atmosphere by smelting or mining or some other processes, cadmium compounds can be associated with respirable-sized airborne particles and can be carried long distances. It is naturally occurring in the environment as a pollutant that is derived from agricultural and industrial sources. The oxidative stress induced by this xenobiotic may be one of the mechanisms responsible for several liver and kidney diseases. Cadmium decreases the activity of DNA repair enzymes, influencing cell cycle proliferation and stimulating carcinogenesis. Res. Cadmium is released into the environment mainly through industrial waste streams, leaching of landfills … The main target in cadmium intoxication.

Cadmium is mined and then released into the environment mainly through the air during smelting. Epidemiological data suggest that occupational and environmental cadmium exposure may be related to various types of cancer, including breast, lung, prostate, nasopharynx, pancreas, and kidney cancers. 2. Vitamin C Protects Porcine Oocytes From Microcystin-LR Toxicity During Maturation. Cadmium toxicity almost always goes undetected by most traditional physicians. D. All of the above.
NIH Due to its low permissible exposure in humans, overexposure may occur even in situations where trace quantities of cadmium are found. -, Genchi G., Sinicropi M.S., Carocci A., Lauria G., Catalano A. Mercury exposure and heart diseases. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. as a neutron absorbent in nuclear reactors. B. Other sources of airborne cadmium include burning fossil fuels such as coal or oil and incineration of municipal waste such as plastics and nickel-cadmium batteries (which can be deposited as solid waste) (Sahmoun et al. D. None of the above. CE Renewal Date: May 12, 2011
Mitochondria damage is highly plausible given that these organelles play a crucial role in the formation of ROS (reactive oxygen species) and are known to be among the key intracellular targets for cadmium. 2010 Sep 15;198(1):49-55. doi: 10.1016/j.toxlet.2010.04.013. Curr Med Chem. 2010;2:329–333. C. Is never found in meats. Into soil by its presence in phosphate fertilizers and sewage sludge. A. Get the latest public health information from CDC: https://www.coronavirus.gov. eCollection 2020. Certain plants, such as tobacco, rice, other cereal grains, potatoes, and other vegetables, take up cadmium from the soil. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure. 2010;84:501–520. Being a simple chemical element, cadmium is persistent – it cannot be broken down into less toxic substances in the environment. The authors declare no conflict of interest. Cellular mechanisms of cadmium-induced toxicity: a review. 3. | Cadmium accumulates in plants and animals with a long half-life of about 25-30 years. DNA methyltransferase, histone acetyltransferase, histone deacetylase and histone methyltransferase, and micro RNA are involved in the epigenetic changes. The liver and kidneys are extremely sensitive to cadmium's toxic effects. Human Health. To review relevant content, see Cadmium in the Food Chain in this section.

Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Mutat Res. Int J Environ Health Res. Biometals. Cadmium can accumulate in liver, kidneys and bones, which may serve as sources of exposure later in life. A. 2017;14:74 doi: 10.3390/ijerph14010074. Cadmium concentrations in drinking water supplies are typically less than 1 microgram per liter (μg/L) or 1 part per billion (ppb) (ATSDR 1999). 2005). C. Various industrial uses such as in plating, NiCd batteries, pigments and plastics.
